    摘要： An apparatus for molding a plurality of articles of hardenable material such as plastic which requires each article to be maintained under heat and pressure for a cure interval. A molding press is utilized wherein there is placed a first open mold assembly having spaced die halves between supporting mold platens. At least one of the die halves has a resilient pressure pad between the die and the mold platen supporting the die half. The press is closed to maintain the mold platens in a first force applying position having a slight gap between the die halves and locking the platens in the first position. The mold assembly is removed while in its first locked position from the press and gas from the curing material is evacuated through the gap between the die halves while heating the material. The mold assembly in its first locked position is again placed in the press and the press is closed to unlock the mold assembly and apply and maintain a second molding force greater then the first molding force and sufficient to completely close the die halves to a second position for curing the material and compress the resilient pressure pad. The mold platens are locked in the second position whereby the pressure pad will apply internal forces against the dies to maintain the correct curing pressure in the event of shrinkage of the cured material. The mold assembly is removed from the press in its second locked position and the material is cured under pressure and at elevated temperatures for the correct time interval to form the article. Finally, the mold assembly is unlocked and the article is removed therefrom.

    摘要： A mounting apparatus for use with a television deflection yoke adapted for transverse adjustment on a kinescope comprises an insulator adapted to be fixedly mounted on the neck of the kinescope at the rear of the insulator. The insulator receives horizontal and vertical deflection coils, and a magnetically permeable core, to form a deflection yoke. A plurality of yoke position orientation and fixing means are mounted to the front of the insulator. The position orientation and fixing means each comprise a guide means incorporating a first engagement means. A member, incorporating second engagement means, is slidably disposed within the guide means. The first and second engagement means cooperate to allow the deflection yoke to be securely held in its adjusted position when the sliding member of each orientation and fixing means is in abutment with the kinescope.

    摘要： A torsionally de-coupled engine mount system for use in tilt rotor aircraft applications is disclosed, in which an engine is mounted at its forward end to a prop rotor gear box by means of a forward mount that is a simple adapter fitting, and at its aft end to a pylon assembly by an aft mount that is a simple bi-pod fitting. The forward mount counteracts forces and moments in six degrees of freedom, but the aft mount only counteracts lateral and vertical loads. The contribution from the engine to the overall dynamic response of the aircraft is tuned by selectively tailoring the size, shape, weight, and material of the forward mount. The engine mount system torsionally de-couples the engines from the prop rotors, thereby preventing rotor torque from being induced into the engines. In addition, the contribution from the engines to the overall dynamic response of the aircraft can be tuned by selectively tailoring the size, shape, weight, and material of the forward mounts between the engines and the transmissions.

    摘要： A skid landing gear for a helicopter, in which the directional stiffnesses of the cross members of the skid landing gear have been de-coupled from one another, such that optimization of the longitudinal stiffness of the cross members may be performed independently of the optimization of the vertical stiffness and fatigue life of the cross members. In order to de-couple the stiffnesses in the skid type landing gear, two approaches are employed. In the first approach, the skid landing gear has non-symmetric-section cross members and/or distribution of different materials within the cross-section for de-coupling the vertical stiffness of the cross members from the longitudinal stiffness, such that placement of the ground resonance frequency may be optimized, while retaining the vertical stiffness properties essential for optimizing vertical energy attenuation and fatigue life. In the second approach, mounting devices are employed that provide compliance in selected directions, thereby de-coupling the directional stiffnesses.
